RAILWAY-STATION SIGNAL.

SPECIFICATION forming part of Letters Patent No. 573,047, datd December1 5, 1896. Ap li ati fil d March 26,1896. Serial No. 584,927. (Nomodel.)

[0 at whom it may concern:

Be it known that I, ARTHUR AUGUSTUS SPRAGUE, a citizen of the UnitedStates, and a resident of New York city, county of New York, andState ofNew York, have invented certain new and useful Improvements inRailway-Station Signals, of whichthe following is a specification,reference being had to the accompanying drawings,formingapartthereof, inwhich similar letters of reference indicate corresponding parts.

This invention relates to an improvement in railway-station signals; andit consists in certain improvements in the construction de scribed andclaimed in the United States Pat? ent No. 317,590, granted to me May 12,1895.

The invention will be hereinafter fully de scribed, and specifically setforth in the annexed claim.

In the accompanying drawings, forming 'part of this specification,Figure l is a perspective View of my improved signal, showing the sameset at danger. Fig. 2 is a longitudinal sectional elevation showing thedevice partly closed, and Fig. 3 is a sectional plan view on a line 00as of Fig. 2.

In the practice of my invention, to the front wall a of a suitablesignal box or house A is secured an outwardly projecting shelf B, whichshelf is mounted upon a bracket O,the said bracket being painted red asan indication of danger.

Upon the outer end of the shelf B is mounted a casing D, the outer endof which casing has open sides with transparent windows 0 affixedtherein, and the outer end of said casing has hingedthereto atransparent door a, through which door a lamp E may be passed and placedwithin the casing to act as a nightsignal.

The bracket 0 and the casing D are projected at right angles from thefront of the signal-box A across the track 1, whereby the signal can beviewed from either direction, and it may also be seen from the end ofthe casingthrough the medium of the transparent door 0.

The whole casing D is composed of opaque material, with the exception ofits windows a and its transparent door 0. Within the easing D is mounteda sliding framework F, which comprises a rear wall f and side walls f,the said sidewalls having colored-glass lenses f secured therein. Thissaid frameworkis mounted upon an :1 slides freely within 5 5 groovedrails d, secured to the side Walls of the casing D.

Hinged to each side of the bracket 0 are doors G, which are adapted tofold, respectively, upon the said bracket and conceal its entire surfaceand to extend at right angles therefrom, whereby its surface may beexposed to view. As a means for operating the said doors and theframework F simultaneously I provide a longitudinallyextended rod H,which is mounted at its outer end. upon a hanger h and is pivotallyattached at its inner end to'a leverI. This said lever is fulcrumed atits upper end upon a bearing 2', secured to the side wall a of thesignal-box A.

Secured to the rod II at aboutthe center thereof is a collar h, which isprovided with two outwardly-projecting arms 7L2, which said arms are inengagement with rods g, which connect with brackets 9 upon the doors G.The rod II is further provided with adjustable stops j, which engagewith the forked end j of the lever J. This said lever is pivotallyattached to bearings 7' of the casing D, and it is further provided atits upper end with a forked projection 7' which engages with a cross-barf 3 of the framework F,whereby said framework may be operatedlongitudinally. The lower end of the lever I bears upon a rail K, whichis provided with slots is, 8 5 adapted to engage with the said lever andlock the same in position. This said rail is securely mounted to theside wall a of the signal-box A. Said wall is further provided withindicators is, which indicators bear, respectively, the colors of whiteand red and are adapted to guide an operator in adjusting the lever I.

In the operation of the device, when it is desired to set the signal atdanger and eX- 5 pose the red surface of the doors G and the bracket 0an operator will place the lower end of the lever I opposite theindicatingdisk at the right, whereby the lever I will be locked withinthe right-hand slot of the rail 10c K, thus forcing the framework Faround the lamp E and producing a red light through the lenses fthereof. During the daylight hours the light will be dispensed with, the

colored surface of the bracket 0 and the doors G only being exhibited.When it is desired to set the signal at safety, the lever I will beplaced in engagement with the left-hand slot is of the rail K, wherebythe doors Gwill be folded over upon the bracket 0 and the framework Fwill be contained within the opaque rear portion of the casing D. Theouter faces of the'doors G will be painted white as an indication ofsafety, and they may further be supplied with the names of stations, ifdesirable, as illustrated in Fig; 2 of the drawings.

' Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

In a railway-station signal, a horizontallyextended colored board orbracket having colored doors hinged to either side thereof and a casingadapted to contain a lamp mounted thereon, said casing being opaque inits rearward portion and having transparent windows in the forward endthereof, and a sliding framework carrying colored lenses mountedtherein; in combination with a horizontally-extended rod which is inengagement with a double-forked lever adapted to operate the saidsliding framework and with rods connected to the said doors, whereby thedoors and framework may be simultaneously operated by oscillatorymovement imparted to the said rod which rod is connected at its innerend to an operating-lever, substantially as shown and described. 7 V

. In testimony that I claim the foregoing as my invention I have signedmy name, in presence of two witnesses, this 21st day of March, 1896.
